Signal suspension and resumption in DSL systems

a communication system and signal technology, applied in the field of multi-channel communication systems, can solve the problems of crosstalk, affecting the dsl communication between the co and the customer premises, and the subscriber line communication system is susceptible to downlink, so as to limit the harmful effects of crosstalk and reduce the amount of dsl re-initialization

[0034]U.S. provisional Application No. ______, “Signal Suspension And Resumption in DSL Systems” filed Jun. 4, 2008, by Adriaan J. de Lind van Wijngaarden, Jochen Maes, Carl J. Nuzman, and Danny van Bruyssel is incorporated herein by reference in its entirety.

[0035]FIG. 1 schematically illustrates a portion 10 of one example of a telephone system that supports voice and DSL communications between a central office (CO) 12 of a DSL service provider or a local telephone company and a set of customer premises (CP) 141, 142, . . . , 14N. The CO 12 has a set of DSL modems 241, 242, . . . , 24N centrally controlled by a controller 28. Each CP 141, 142, . . . , 14N has a DSL modem 181, 182, . . . , 18N, local wiring 22 and optionally telephones 201, 202, . . . , 20N. The DSL modems 241, 242, . . . , 24N of the CO 12 and the DSL modems 181, 182, . . . , 18N of the CPs 141, 142, . . . , 14N are connected through local-end lines 161, 162, . . . , 16N and the local wiring 22 at the CPs 141, 142...

Abstract

A method includes maintaining temporally parallel DSL data communication sessions with DSL modems of a group via a set of lines. The method includes, in response to substantially stopping to receive DSL communications from one of the DSL modems via one of the lines, transmitting a substantially reduced average power to the one of the lines and monitoring the one of the lines to determine whether DSL communications have restarted being received from the one of the DSL modems. The method also includes resuming the maintaining of the temporally parallel DSL communication sessions in response to the monitoring determining that DSL communications have restarted being received from the one of the DSL modems.

Description

[0001]This application claims the benefit of U.S. provisional Application No. ______, “Signal Suspension And Resumption in DSL Systems”, filed Jun. 4, 2008, by Adriaan J. de Lind van Wijngaarden, Jochen Maes, Carl J. Nuzman, and Danny van Bruyssel.BACKGROUND[0002]1. Technical Field[0003]The invention relates to multiple channel communication systems.[0004]2. Discussion of the Related Art[0005]This section introduces aspects that may be helpful to facilitating a better understanding of the inventions. Accordingly, the statements of this section are to be read in this light and are not to be understood as admissions about what is in the prior art or what is not in the prior art.[0006]Many digital subscriber line (DSL) communication systems are susceptible to downlink and uplink crosstalk between the local-end telephone lines that connect DSL modems of a central office (CO) to DSL modems at customer premises. The crosstalk may be caused, in part, by inductive coupling between twisted p...
